Two strings can be compared for an exact match (including case) using the double equal to operator (==).  The result is a if they match

> print("ABC" == "abc")

false

 

> print("ABC" == "ABC")

True

 

The comparison can be used in control structures such as shown below:

>str1 = "ABC"

> if (str1 == "abc") {

>        print("Strings are identical")

> }else {

>        print("Strings are not identical")

>}

 

      Strings are not identical.
